The alterations are associated with poor outcomes and disease progression. Alterations in metabolic processes are a hallmark of cancer and can lead to a tumor environment that is acidic. As a result, cancer cells must adapt to survive in this inhospitable environment. In a new study published in the journal Cell Reports, Moffitt Cancer Center researchers show that cancer cells in an acidic environment undergo lipid synthesis and accumulation. The team identified the key signaling molecules responsible for these changes and discovered that these alterations are associated with poor outcomes and disease progression among breast cancer patients.

Cancer cells undergo numerous changes that promote cell survival and continued growth...

Healthy adults who eat a diverse diet with at least 8-10 grams of soluble fiber a day have fewer antibiotic-resistant microbes in their guts, according to a study published by Agricultural Research Service scientists and their colleagues in mBio.

Microbes that have resistance to various commonly used antibiotics such as tetracycline and aminoglycoside are a significant source of risk for people worldwide, with the widely held expectation that the problem of antimicrobial resistance (AMR) — the term that refers to bacteria, viruses, and fungi th...

Imagine being able to measure your blood sugar levels, know if you’ve had too much to drink, and track your muscle fatigue during a workout, all in one small device worn on your skin. Engineers at the University of California San Diego have developed a prototype of such a wearable that can continuously monitor several health stats — glucose, alcohol, and lactate levels — simultaneously in real-time.

The device is about the size of a stack of six quarters. It is applied to the skin through a Velcro-like patch of microneedles, that are each about one-fifth the width of a human hair...

In a study that followed hundreds of mice over their lifespans, calorie restriction combined with time-restricted eating boosted longevity. One recipe for longevity is simple, if not easy to follow: eat less. Studies in a variety of animals have shown that restricting calories can lead to a longer, healthier life.

Now, new research suggests that the body’s daily rhythms play a big part in this longevity effect...
